Do pop rivets allow you to complete riveting operations from one side of the metal?

• A. False
• B. True
• C. Only for thin metals
• D. Not always

Answer: (B)

Pop rivets (blind rivets) are designed to be installed from one side. You insert the rivet through the holes, then use a blind rivet gun on the accessible side to pull the mandrel. As the mandrel is pulled, the rivet body expands on the opposite side, forming the second head and clamping the sheets together. When the rivet is fully set, the mandrel snaps off. Because the setting action happens from the accessible side, you don’t need access to the far side to complete the joint.
